To all whom it to a3 concern Be it known that We, JOHN lsenrrnn and JAMES CHAPMAN, subjects of llling George V of Great Britain, residing at all) Bowling street, Dunedin, in the Dominion of .llei'v Zealand, have invented certain new and use- :Eul improvements in Hatpins. of which the tollowin is a specification.

The ooject oi the invention is to provide a turcated gin with means thereon to clamp the prongs together so that they resemble one pin tor the purpose oi? facilitating their entry through the hat.

In the accompanying drai'vings, the figures illustrate a bifurcated pin, and referring thereto,

Figure l is a View showing; the clamping head near the points of the pin, holding the prongs in a position so that they appear as one pin, to facilitate their entry.

Fig. 2 a View 01" the pin showing the clamping head near the the prongs, the pn having been p i the said clamping head to permit the prongs to spring apart.

Fig. 3 is a part View of a pin showing a looped head with the clarnping head near the socket end oi the prongs.

The following; description With reference to the draw' hut it more than. two prongs are won d, me 2. than one piece of Wire must he used in the construction.

The hat pin is preferably constructed from one piece oi? Wire, the cross section thereof heing approximately sen1i-circular. the Wire hating necessary resiliency, so that when bent at l to lit Within the socket 2. the position the prongs 3 and l. when not under the influence oi the clan1plug head 5.. would be normally in. the position illustrated in 2, but when under the influence of the said head 5. the position of the prongs would he as indicated in l l.

A suitable fastening is provided. such as illustrated at 6, having; one end attached to a hug 7 of the socket meinher and the other end attached to a lug 8 of the clampinp; head to prevent the said head from becoming disengaged; the clamping head, the

fastening means, and the head 9 ot the pin may he plain or ornamental to suit the taste. in .Fig. 3, the construction of the pin can he more readily traced as ocing formed from one piece or Wire; a loop 9 formed instead of employing a head 9. The prong members 3 and Where they project from. the loop 9 are brought closely together as indicated at 9 so that the prong members, when not closed, as indicated in F 2, under the inl'hienee oi the clamping head 5, would he held together at the neck of the pin by the transference of the said clamping head member 5. to the neck the said head n1einher becoming an equivalent to the socket illustrated in Fl 's. l and 2.

"ll ith the prey on 01 the 5, the 1 of tee points through the hat is facilitate the progress of pushing; the sired position, the said clamping head 5 automatically shi s from the point of the pin illustrated in Fig. l. to the position illustrated in F 2, whereupon the prongs spread through the hair and virtually hecoine o. substitution for two pins.

Vi e aware that is old to provide a bifurcated hatpin having); means for moving the bifurcations together and do not lay hroad claims to such structure but What We do claim and desire to secure by Letters Patent i:-

A hat pin. comprising 2. pair of z-rongs formed from one piece of resilient material substantially semi-circular in cross section, hent hack upon itself interi'nediate its ends, a head arranged to receive and clench said bent portion, and a head slidahly mounted on said prongs and arranged to move said prongs into engagement V, th one another to form a unitary substantially cylindrical member.

In testimony whereof We have hereunto set our hands in presence of two subscribing Witnesses.
